Sketch and Interpret Wave Graphs
Figure 5.16 shows the profi le of a transverse wave at a certain instance.

Direction of propagation

Figure 5.16 Profi le of a transverse wave

Particles along the wave oscillate up and down about the Simulation of a wave profi le
equilibrium position. Scan the QR code given to observe the
change in displacement of the particles. Two types of graphs
can be drawn to show the variation of the displacement of wave
particles, which are graph of displacement against time and http://bt.sasbadi.com/p4180a
graph of displacement against distance.

Activity 5.5 ICS

Aim: To sketch a graph of displacement against time and Video on method of sketching
a graph of displacement against distance a graph of displacement
Instructions: against time
1. Group in pairs.
2. Scan the QR code to observe the method of sketching
a graph of displacement against time and a graph of
displacement against distance. http://bt.sasbadi.com/p4180b
3. Sketch a graph of displacement against time for a
wave with: Video on method of sketching
(a) Amplitude, A = 5 cm a graph of displacement
(b) Period, T = 0.4 s against distance
4. Sketch a graph of displacement against distance for a
wave with:
(a) Amplitude, A = 5 cm
(b) Wavelength, λ = 4 cm http://bt.sasbadi.com/p4180c
